In reference to cross efficiency evaluation using prospect theory how do we rank the DMUs incase of CCR Model when efficiences of DMs are same ?

20 May 2019 0 6K Report

Suppose there is a problem where there are 2 inputs as well as 2 outputs and DMU's corresponding to it and after calculating the efficiencies using CCR model there are 4 DMU's which have efficiency equal to 1.

In order to use PCE model best DMU as well as worst DMU is required .Worst DMU can be found with DMU with worst efficiency .My question here is how do we determine BEST DMU as there are 4 DMU's with efficiency equal to 1?
